3 Property of Arrayed Fiberoptics Corporation Outline Analysis of current technologies Arrayed Fiberoptics Technology Products and Applications Epoxy-Free Fiber Arrays Summary

4 Property of Arrayed Fiberoptics Corporation Components for DWDM Network Thin film filters Fiber gratings AWGs Diffr. gratings Interleavers Mux/Demux modules Isolators Tap couplers Pump lasers Gain equalizers Integrated amplifiers SOAs Switches Attenuators Circulators Couplers Add/drop modules Source lasers (CW, DML, EML,Tunable) External modulators Wavelockers Tx/Rx modules Arrayed Fiberoptics technology is applicable to many of these devices Mux/DemuxSwitching long fiber (80 Km) Transmitters Amplifiers

5 Property of Arrayed Fiberoptics Corporation Fiber Components Optical “Heart” Fiber Interface All fiberoptic components have two parts: 1)Optical “heart” which provides functionality 2)Fiber Input/Output interface Fiber Interface Manufacturing Cost Optical “Heart” ~ 15% Fiber Interface ~ 85% 1)Optical “heart” is only ~15% of the total cost of a fiberoptic component 2)Fiber interface or “packaging” is ~85% of cost 3)Companies have focused on optical “heart” and traditional packaging

6 Why the high cost? Planar Lightwave Circuit Fiber Array Waveguide Micro-Optics GRIN Lens Fiber Lens Laser Diode  All current technology involves individual fiber alignment  Sub-micron alignment is neccessary in many cases  Many expensive piece parts required  Fiberoptic components cost hundreds of dollars each

7 Property of Arrayed Fiberoptics Corporation The Breakthrough: VFI – Vertical Fiber Integration Apply LARGE-SCALE semiconductor manufacturing technologies to fiber alignment align 2 = align 20, Bond multiple wafers together to VERTICALLY create high-value 3-D FULLY integrated devices. 3.Passively insert fibers into pre-aligned high-precision sockets after singulation 4.Covered by multiple issued and pending patents The differentiator is full wafer-scale integration

8 Property of Arrayed Fiberoptics Corporation VFI Process Overview Wafer Alignment Bonding Singulation Fiber Incorporation

9 Property of Arrayed Fiberoptics Corporation VFI Advantages Wafer-scale process dramatically reduces cost Extremely high precision fiber alignment Inherently produces component arrays Very compact devices High thermal stability Inherent hermetic sealing Applicable to a wide range of telecom devices
